Link? I also proposed this on this list (see the response in the tree datastructures thread) along with more elaboration on IRC. If multiple people are coming up with it thats a good sign that it it might actually be viable. :) I was going for a slightly different angle and pointing out that the proofs would mean that a node doing validation with TxOUT tree which hasn't personally wittnessed the complete history of Bitcoin actually has basically the same security— including resistance to miners creating fake coin in the past— as a full node today because in order to get away with a lie every single node must conspire: It's adequate that only one honest node wittness the lie because once it has the proof information is hard to suppress. To save people from having to dig through the public IRC logs for what I wrote there: --- Day changed Thu Jun 21 2012 15:10 < gmaxwell> etotheipi_: amiller: an interesting point with all this txout tree stuff is that if you join the network late and just trust that the history is correct based on the headers, any other node who has witnessed a rule violation in the past can prepare a small message which you would take to be conclusive proof of a rule violation and then ignore that chain. 15:11 < gmaxwell> e.g. if someone doublespends I just take the conflicting transactions out and the segments connecting them to the chain... and show them to you. And without trusting me you can now ignore the entire child chain past that point. 15:13 < gmaxwell> This fits nicely with the Satoshi comment "It takes advantage of the nature of information being easy to spread but hard to stifle" ... it would be safe to late-join a txout tree chain, because if there is only a single other honest node in the world who was around long enough to wittness the cheating, he could still tell you and it would be as good as if you saw it yourself. 15:17 < gmaxwell> (this is akin to the provable doublespend alert stuff we talked about before, but applied to blocks) ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
